To IZ'Z (whom t concern Be it known Sth-at il, Enom BAINTER,

va l.citizen .of :the Uni-ted States, residing :at

Good Hope, in the county ofFayetteVand State :of @lhio, ihave invented fcertain new and useful Improvements in Rollers, of which the following isa specification.

My invention relates to rollers and fis particularly directed to an improvement in rollers for use in breaking clods lof earth, but desirably of such a nature that the earth being operated upon will not be packed too closelyy which is undesirable under certainz circumstances, such as in the treatment of farm lands. In the attainment of such a roller, I have constructed my roller with a central hollow which does not detract from the necessary strength o-f the roller, but gives it sufiicient lightness to preclude the packing mentioned.

My invention further contemplates the provision of end reinforcing elements for the roller utilized, which end reinforcing elements are desirably flush with the rolling surface of the roller and secured'with sufficient rigidity thereto to preclude chipping or breaking of the edges of the roller.

Still a further object of my invention is to form the body of the roller about a core of strawboard or similar material, similar in the sense that it must be light and inexpensive. a

The preferred embodiment of my invention is shown in the accompanying drawings, in which similar characters of reference designate corresponding parts, and in which- Figure 1 is a plan view of my roller structure wherein there are utilized dual rollers, but having the same essential characteristics of a single roller and showing o-ne of the rollers in longitudinal horizontal section, Fig. 2 is a section taken on line 2 2 of Fig. 1, Fig. 3 is a section taken on line 3 3 of Fig. 1, and Fig. 4 is an end view of the structure shown in Fig. 1.

In the drawings, there is shown an angle iron framework of rectangular form and comprising transverse members 1, longitudinal rods 2, embracing longitudinal rod 3 and a bracing center piece and bearing 4. The framework carries a handle 5 which is desirably bolted thereto as at 6 and 7. This produces a strong framework member and this member carries depending trunnions 8V upon its transverse pieces, which depending triinnions serve to support ibearings 9 which are of any desired and essential form. Extending longitudinally of `the frame through all lof the bearings carried 'by the :trunnions as mentioned, is a shaft l10 held :against rotation "by set screws as shown at 11 'in Fig. 4. f

The rollers are videntical lin structure and will `be 4'described accordingly. @Each Yroller comprises a lho'llow cylindrical Acentr-al core 12 of strawboard, andl a surrounding body of concrete L3 desirably 'reinforced at yits ends by triangularly disposed reinforcing Vrods 14 which are preferably in the form of twisted rectangular bars of metal. The ends of the body .portions of these rollers are braced and reinforced by disk-like plates 15 having annular undercut flanges 16 upon their inner peripheral edges which are in turn broken at intervals by dove-tail lugs 16a. This structure of undercut flanges and dove-tail lugs is peculiarly eflicacious in forming a rm anchorage connection between the concrete and the disk plates. The plates are further provided centrally with frusto-conical formations 17 which are bored, and being concentrically disposed and concentrically bored, serve as extended bearings for the rollers upon the shaft 1() preventing uncertainty of rotation and wabbling liable to result from wear of the parts of a roller of this structure. These plates being anchored to the concrete body portion as aforesaid, are further held in rigid position by longitudinal bars 18 and nuts 19.

From the above, it will be apparent that l have provided a simple structure of roller which may be used either in dual form or in single roller form, but which is essentially compact and strong and will not readily lose its centered and proper position of operation. Furthermore, the parts are so formed structurally and so related to each other as to insure against accidental separation or breakage due to stress of work.

What I claim, is

1. A roller structure comprising a mono-y lithic roller element, a light hollow core for said element, cap plates having integral extended bearings for said element, annulaiundercut flanges formed on the peripheral edges of said cap plates, said bearings and flanges being embedded in the ends of the roller element.

2. A roller structure comprising a monolithic roller element, a light hollow core for losl said element, cap plates having tapered integral extended hearings for said element, annular undercut flanges formed on the peripheral edges or' said cap plates, spaced dove-tailed lugs on said flanges, said lugs, flanges and hearings being embedded in the ends of the roller element.

A roller structure comprising a monolithic roller element, a light hollow core for said element, reinforcing bars in the ends of said element extending from the ends of said element to the ends of the core, cap plates having integral extended bearings for said element, an operating shaft extending through said element and said bearings, coinpleinental apertures in said element for receiving said hearings and rods extending lirough said element and said plates for holding said plates in position.
